-- =====================================================
-- NOTES AND NEXT STEPS
-- =====================================================
-- 
-- 1. RLS Policy Optimization:
--    This migration fixes a few example policies, but there are 100+ policies
--    that need the same fix. Consider creating a script to systematically
--    update all policies that use auth.uid(), auth.role(), or current_setting()
--    to wrap them in (SELECT ...).
--
-- 2. Multiple Permissive Policies:
--    Many tables have multiple permissive policies for the same role/action.
--    Consider consolidating these into single policies using OR conditions
--    for better performance.
--
-- 3. Unused Indexes:
--    The linter identified many unused indexes. Review these carefully before
--    dropping, as they may be used by queries that haven't run yet or by
--    application code that's not currently active.
--
-- 4. Function Search Path:
--    This migration attempts to fix search_path for many functions, but some
--    may fail if the functions don't exist or have different signatures.
--    Review the output and fix any remaining functions manually.
--
-- 5. Extension Schema:
--    Moving pg_trgm requires manual intervention as it affects existing indexes.
--    Plan this migration carefully.

-- =====================================================
-- NOTES
-- =====================================================
-- 
-- This migration optimizes RLS policies by wrapping auth functions
-- in SELECT subqueries. This prevents PostgreSQL from re-evaluating
-- these functions for each row, significantly improving query performance.
--
-- The pattern changed:
--   OLD: auth.uid() = user_id
--   NEW: (SELECT auth.uid()) = user_id
--
-- This is especially important for tables with many rows and frequent queries.
--
-- Note: Some policies may reference functions like basejump.has_role_on_account()
-- which already handle auth internally. These don't need wrapping but should
-- be reviewed for performance.
